Safety light curtains and limit switches

AutomationDirect now offers machine safety devices for use in industrial applications. The YBB-14 series has a 14-mm sensing resolution for finger-size protection and an operating distance of up to 3.5 metres, as well as protective heights ranging from 142 mm to 1,045 mm. The YBB-30 light curtains series has a 30-mm sensing resolution for hand protection and an operating distance of up to 12 metres. Protective heights range from 279 mm to 1,827 mm. All safety light curtains have Type 4 and Cat 4 PL e safety ratings and are IP65 rated.

AutomationDirect has also added a line of machine guarding safety switches to detect unsafe conditions and isolate power. Normally-closed contacts are used for a positive break, and redundant normally-closed contact and normally-open feedback outputs are available. The safety switches cannot be easily defeated and all units have CE, UL and CSA approvals. Four bases are available: 30-mm plastic, 50-mm zinc alloy, 40-mm aluminum and 60-mm aluminum. Four types of interlocks are available for common safety applications, including tongue (key), shaft hinge, lever hinge interlocks and pull cord actuators with reset for emergency stop or without reset for simple stop.
